On June 15, 2006, President George W. Bush signed a Presidential Proclamation that created the Northwestern Hawaiian Islands Marine National Monument. At that time, it was the largest fully protected marine conservation area on the planet. A year later, the Monument was given its Hawaiian name, Papahānaumokuākea.
In August 2016, President Barack Obama quadrupled the size of Papahānaumokuākea Marine National Monument. It now covers 582,578 square miles, twice the size of Texas.
President George W. Bush established the Papahānaumokuākea Marine National Monument in 2006.
